    Abstract: Curable elastomer compositions are described which include particles of reclaimed elastomeric material having a particle size of 60 mesh or smaller, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1. Curable styrene butadiene rubber (SBR) elastomer compositions are also described which include reclaimed elastomeric material, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1. The cured elastomeric compositions exhibit improved physical properties compared to elastomer compositions containing reclaim material which employ conventional high sulfur cure systems.

    Abstract: A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100 C such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.

    Abstract: Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.
